MATHEW H. KEYS, OF OXFORD, MISSISSIPPI.

CULTIVATOR AND COTTON-CHOPPER.

SPECIFICATION forming part of Letters Patent No. 265,968, dated October17, 1882.

Application filed July 29, 1852.

To all whom it may concern:

Be it known that I, MATHEW H. KEYS, of Oxford, in the county ofLafayette and State of Mississippi, have invented certain new and usefulImprovements in a Combined Cultivator and Gotton-0hopper; and I doherebydeclare that the following is a full, clear, and exact descriptionof the invention,which will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

This invention relates to a combined cultivator and cotton-chopper, andhas for its ()bjt ct to provide a simple, inexpensive, and efticientdevice.

To this end it consists in certain improvements in the construction andoperation of the same.

In the drawings, Figure 1 is a top view of the machine; Fig. 2, a sideview; Fig. 3, a longitudinal vertical sectional view Fig. 4, atransverse vertical sectional view on the line 00 m, Fig. 1; Fig. 5, afront end view; Fig. 6, a transverse sectional view on theliney y, Fig.1.

Referring to the drawings, A designates a substantially -shape frame,comprising side beams, B B, and rear cross-piece, G, the Whole beingmounted on drive-wheels D D, fixed on the rotary axle E,jonrnaled inbearings about midway on beams B B. At the front ends of thelatter isarranged a cross bar or rod,F,on whichis hinged a centralcultivator-shank, G, on each side of which are also hinged platforms HH, extending rearwardly to axle E, each provided with projectingbrackets I 1, adapted to rest on the axle and support the rear end ofthe platform, each of the latter being provided with a double series ofslots, J K. In these slots are adapted to be secured by a transversepivot pin or bolt, L, the U-shaped shanks M of cultivators N, which arearranged one pair under each platform. To the shanks of each pair ofcultivators are secured the ends of a chain or rope, 0, its centralportion passing over a pulley, P, in a block, Q, hinged on bar F andadapted to slide thereon. Thus any of the cultivators N will readilygive to an obstruction, and while one is forced back the other will bedrawn forward by the chain, so that there will be no strain on theshanks.

(No model.)

B It are rods sliding in staples or guides S on beams B B, and providedat their front ends with an angular plate, T, which is adapted to passover the platform and retain the same down. The forward movement of theplates T is limited by a springplate, U, arranged one on each beam B,and the downward tension of these plates U on plates T serves to retainthe latter in position against anyjolting, and the plates 1 have to bedrawn from under thespringplates.

V V are two standards, arranged on beams B B forward of the axle E, andhaving bearings for a transverse rotary rock-shaft, W, from which extendchains or ropes X X, detachably secured at their lower ends to theplatforms H H. Thus when the shaft W is turned the chains XX will windupon and elevate the rear ends of the hinged platforms carrying thecultivators. When it is not de sired to raise the platforms the chains XX .may be detached therefrom by the hooks or catches Y at theirlower-ends.

To operate or turn rock-shaft W it is provided with a chain or rope, Z,at one end, which extends rearwardly and is wound round a pulley, A,fixed to a shaft, B, journaled in a bracket, 0, arranged on one of beamsB. Shaft B may be turned by a wrench or key to wind cord Z and turnshaft V.

Fixed on rotary axle E is a gear-wheel, D, at the side of which ismounted a standard, E, having a perforation or bearing, F, for the axle,and adapted to turn thereon. In its rear end the standard E is formedwith a bearing, G,for a rotary shaft, H, carrying a small fixedgear-wheel, l, meshing with gear-wheel D, and a disk, J, carrying theradial choppers K. The rear end of shaft H is housed in boxing L,arranged on cross-piece O of the frame. M is a chain or rope extendingfrom the front end of standard E to the rock-shaft W, so that whenthelatter'is turnedthe standard carrying the chopper-shaft may beelevated, the rear end of shaft H being guided in boxing L.

N is the draft bar or tongue, which is bifurcated at its rear end, thearms 0 0 thus formed being hinged on front bar or rod, F, at each sideof the central cultivator-shank, G, nicely inclosing the same andpreventing it 2 assess front rod, F, is secured in brackets P 1? on theend of side beams, B B, its ends Q, Q being screw-threaded and adaptedto receive nuts 1t R, which bind against beams B B and retain rod F inposition.

The operation and advantages of my invention will be readily understood.

The device is very convenient and easily operated, and its parts arereadily adjustable.

I claim and desire to secure by Letters Patent 1. The combinatiomwiththe frame having the axle and cross front rod or bar, of one or moreplatforms, hinged on said rod at their front ends and supported on theaxle at their rear ends, said platforms carrying the cultivators andadapted to be elevated, as set forth.

2. The combination, with the frame having the front cross rod or bar, onwhich is hinged and adapted to slide oneor more 'iulley-blocks, of oneor more platforms hinged on said front rod and provided uithsertesofslots, in which the cultivator-shanks are hinged or pivoted, and theconnecting chain or rope secured to the cultivators and passing overthepnlley, as set forth.

3. The combination, with the frame having the front cross bar or rod, ofthe two platforms hinged on the latter, one at each side, andcarryingthe hinged or pivoted Cultivators, and the central cultivatorhinged onsaid front rod between the platforms, as set forth.

4. The combination, with the frame having the front cross rod or bar andcarrying the rock-shaft in rear thereof, of one or more platforms hingedon said front rod, and connected at their rear ends to the rock shaft bya chain or-cord extending up and adapted to Wind round the latter toelevate the platforms on their hinges, as set forth.

5. The combination, with the frame comprising the side b'eams having thestandards carrying a rock-shaft, one beam beingprovided with a brackethaving bearings for a shaft carrying a pulley, the front cross rod orbar, and carrying the axle, of the platforms hinged on the latter andsupported at their rear ends by the axle, the platform-elevating chainsor ropes, and the rock shaftoperating chain or rope, as set forth.

6. The comhinatiomwith the rod carrying a plate, T, at its end,ofaspring-plate, U, to limit the movement of plate T, and by itsdownward tension thereon retain itin position, as set forth.

7. The combination, with the frame having the side beams carrying theaxle and cross front rod or bar,ot'theplatforms(one or more) hinged onthe latter and resting on the former, and the rods moving on the beamsand having at their ends angular plates to retain theplatt'orm down, asset forth.

8. The combination of the frame carrying the rockshat't, and having thefront cross rod or bar and the rotary axle, the hinged platformscarrying the forward cultivators, the hinged standard carrying therotary choppershat't, mechanism for operating the latter, and theelevating chains or ropes, as set forth.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two Witnesses.

MATHEW H. KEYS.
